` GEORGE VILLIAM SHAILER, OF VELLINGTON ONE-HALF TO -WALTER ERNEST HALL AN OF SAME PLACE.

, NEW ZEALAND, ASSIGNOR OF D VILLIAM EDWARD WOODS,

SPECIFICATION forming part of Letters Patent No. 595,003, dated December 7, 1897.

Application filed May 14, 1897.

T all zzz/wm, it may cole/cern:

Be it known that l, GEORGE VILLIAM SHAILER, a subject of the Queen of Great Britain, residing at 54 Lambton Quay, in the city of Vellington, in the Colony of New Zealand, have invented an Improved Non-Refill` able Bottle and Stopper; and I do hereby declare that the following is a full, clear, and exact description of the invention.

The object of this invention is to provide a bottle and stopper which cannot be refilled with liquid after its original contents have been extracted.

It is well known in several trades that fraud is practiced to a considerable extent with the bottles and stoppers at present in use and that they are relled with an inferior liquid which is passed off as the genuine article and corresponding with the old brand left upon 2o the bottle. The present invention prevents such frauds in a simple and inexpensive manner.

The object of the invention is carried into effect by molding the bottle with a neck having its lower part of greater diameter than the upper and by molding a shoulder at the bottom of the neck, whereon a washer, preferably of cork, may rest. Into the interior of this washer is forced a stopper having external and annular corrugati'ons to grip into the washer, into the hollow interior of which is fixed another similar washer, which acts as a valve-seat for a valve. The valve is hollow and hermeticallysealed, so as to be of slightly 3 5 lower specific gravity than the liquid contained in the bottle. The top of the valve is recessed conically to receive a ball, and a similar recess is formed in the bottom of a weight which rests upon and holds the valve down lo to its seat. The upper surface of the weight is also recessed conically to receive another ball, and another conical recess is made in the solid top of the stopper. Around the head of the washer apertures are left through i5 which liquid may pass.

For purpose of a full description in detail the invention is illustrated upon the accompanying drawings, to which reference will now be made.

Serial No. 636,5 59. (No model.)

Figure l is a sectional elevation of the neck and upper part of the bottle with the stopper in position. Fig. 2 is a sectional elevation of the stopper. Fig. 3 is a crosssection on line A B, Fig. 2. Fig. 4 is a cross-section on line C D, Fig. 2. Fig. 5 is a section of the washer, showing the position of the weight, valve, and balls when in a horizontal position.

Similars letters refer to similar parts.

Referring to the drawings, the neck 0;/ of bottle a, Fig. l, has its internal diameter increased at its lower part and is molded with a shoulder a2, Whereon the washer b may rest. The stopper c is forced into Washer b either in the act of coi-king the bottle with the ordinary cork cZ or before such corking, and it grips into the washer by means of the annular corrugations c', so that should an attempt be made to extract the stopper the washer will be withdrawn with the same, but only so far as the narrowing portion a3 of the neck a', where the whole will be effectually held and further withdrawal rendered impossible.

Referring now to Figs. 2, 3, and 4, the internal washerfiits within the stopper @,which is recessed for the purpose, and it rests upon the shoulder a2. This washer f forms a valve seat for valve g, the top of which has a conical recess g for ball g2. Feathers g3 guide the valve as it rises and falls and also leave spaces for the passage of liquid. The upper, 8o ends of the feathers are produced as shown to prevent any jamming which might arise by the valve turning slightly to one side. The valveweight g4 is recessed at the top and bottorn to receiveballs g2 and g5, and its diameter is so small as to provide abundant play within the stopper.

The solid top of the stopper is recessed for ball g5 and is cored out to leave apertures g, through which liquid may pass, as shown by the arrows. The upper surface of the stopper has ribs gT to prevent a sucker being applied to withdraw the same.

The stopper may be made of or other suitable material, and washers b and f may be made of cork, lamp-wick, vulcanite, india-rubber, felt, and the like.

To pour out the liquid, it is best to turn the glass, pewter,

neck of the bottle downward with a somewhat quick movement to give a slight jerk to the Weight g4 and release the valve.

The Weight g4 will keep the valve upon its seat when the bottle is turned to a horizontal position, as shown on Fig. 5, and even to an angle considerably beyond the horizontal.

vWhen thus turned over, the Weight g4 falls by rolling upon the balls g2 and g5 and presses the valve upon its seat, as shown on Fig. 5. Should an attempt be made to fill the bottle When turned upside doWn, such action would be frustrated by the valve g being made so light that it would be carried up by the flow of the fluid and close upon its seat.

Points or nibs q9 are form ed upon the Weight g4 to frustrate an attempt made to pour gum or the like into the stopper to stick the valve to the Weight in order to fraudulently fill the bottle When turned upside doWn. Vith this provision the valve will stick upon its seat, and the points giving so little surface for contact will leave the valve upon its seat with the aperture of the bottle closed.

It must be understood that it is not desired to confine the invention to the details hereinbefore set forth, as these may be varied in several Ways by a skilled person Without departing from the spirit of the invention.

What I claim, and desire to secure by Letters Patent of the United States, is

1. In a bottle-stopper, in combination, a valve-seat, a valve, a Weight movable upon balls running in conical recesses and apertures through the sides of the stopper, substantially as and for the purposes set forth herein.

2. In a bottle-stopper, in combination, a valveseat, a valve, a Weight movable upon balls running in conical recesses, apertures through the sides of the stopper and ribs upon the upper surface of the same, substantially as and for the purposes set forth herein.

3. In a bottle-stopper, in combination, a valve-seat, a valve, a Weight movable upon balls running in conical recesses and having points to give small surfaces of contact, and apertures through the sides of the stopper, substantially as and for the purposes set forth herein.
